Yes, please go to the hospital or call 911 (or whatever the # is in Canada). Or call your T, if you have a cell or emergency number. This is an emergency situation. You're disrespecting your body in multiple ways, first the cutting, now unprotected sex with someone who was cruel to you. You don't deserve that. You might believe you do, but you don't. You're a good person who is having some serious health issues. Please take care of yourself and report back.
